When I first started getting into development I took a look at it because I heard of the great money you could get if you were an expert in it. From what I could tell at the time, 5-6 years ago, it was both a lot harder work to even learn anything more modern just due to the lack of a community that had put all of their knowledge online and a risky proposition. The money looked good, but you severely limited the number of places you worked and if the industry ever decided to get off its ass and change over in even low double digit percentages you were likely to be out of work and with skills that didnt really transfer
